In order to obtain the specific genes of snailfish a subtracted cDNA library was constructed, and analysed by sequencing and GenBank search. Among them C90-171 clone was turned out to be genes showing low homology and nonredundant genes. This novel clone was named Gomsin(C90-171). Gomsin was shown to be intensely expressed in the epithelial cells, some mesenchymal cells, and sheaths of muscle bundles in the result of immunohistochemistry. In the cross reaction assay of Gomsin antibody against various human tissues, the Gomsin was strongly expressed in the ductal and acinar cells of salivary glands, which was similar to the expression patterns of proline-rich proteins(PRPs) of human. The antibody raised against the Gomsin was clearly cross-reacted with human salivary PRPs and also recombinant proteins of human PRPs in the Western blot and immunoprecipitation analysis. Contrast to the salivary PRPs, the Gomsin was not easily degraded in the mixed saliva, but rapidly attacked on the cultured keratocytes in vitro. The simulated protein structure of Gomsin was similar to the whorled pattern of PRPs, even though the amino acid sequence of Gomsin was quite different from those of PRPs. These data suggest that the Gomsin is a characteristic matrix protein in the skin and body of snailfish, which is also utilized for the tissue protection in the similar way to the PRPs of human muco-secretory organs.

This study investigated how the larvae of three winter-spawning fishes are adapted in a cold water environment by examining the morphology, digestive system, and swimming ability of larvae from three winter-spawning species (Gadus macrocephalus, Liparis tanakae, Hexagrammos agrammus). Data were collected at hatching and first feeding. The results were compared with repored data on several non-winter-spawning species. Mean total lengths at hatching (${\pm}SD$) were $4.35{\pm}0.11mm$, $5.26{\pm}0.08mm$, and $7.48{\pm}0.35mm$ for G. macrocephalus, L. tanakae, and H. agrammus, respectively. Three winter-spawning fishes had well-developed digestive tracts after hatching than those of non-winter-spawning fish larvae. Yolks were intact until 5 days post-hatching in all three species, indicating that they had longer mixed-feeding periods compared with fishes spawned during other seasons. G. macrocephalus, L. tanakae, and H. agrammus larvae had superior cruise and burst speeds (measures of swimming ability) than non-winter-spawning larvae. We conclude that the unique characteristics of these three winter-spawning species are naturally selected adaptations under lower water temperature in winter.

Species composition and seasonal variations in abundance of fishes in the Nakdong River estuary were investigated using an otter trawl seasonally from September 2001 to July 2002. These data were compared with those obtained before the construction of the estuary barrage in 1987. A total of 3,648 fishes that comprised 30 species in 21 families were collected. Acanthogobius flavimanus and Leiognathus nuchalis predominated, and they were responsible for $71.2\%\;and\;67.8\%$ in the number of individuals and biomass, respectively. The next abundant fish species were Platycephalus indicus and Liparis tanakai. Compared with data obtained before the construction of the estuary barrage in 1987, abundances of Acanthogobius flavimanus, Platycephajus indicus, Liparis tanakai, Tridentiger trigonocephalus and Lateolabrax japonicus increased, while those of Pholis fangi, Repomucenus valenciennei, Sardineila zunasi and Scomber japonicus decreased. These results seems to be related to change of sediment environment caused by irregular discharge of freshwater with variation of sea water movement in the Nakdong River estuary.

Stomach contents of snailfish, Liparis tanakai, caught in the Nakdong River Estuary were examined quantitatively. Liparis tanakai was a bottom feeding carnivores, and showed an almost strict specialization on shrimps and fishes. Shrimps and fishes accounted for 74.3% and 19.8% of the overall stomach contents, respectively. The most selected prey species was Cragon affinis for all fish size classes. The snailfish' s diets included minor quantities of crabs, amphipods, mysids and isopods. Small individuals(4~10 cm SL) consumed mainly shrimps which accounted for approximately 90% of the stomach contents. However, the portion of the diet attributable to shrimps decreased steadily with increasing fish size, and this decrease was paralleled by increased cosumption of fishes. For 31~45 cm individuals, fishes constituted over 30% of the stomach contents, while shrimps made up approximately 60% of the diet.

A single specimen (373.2 mm SL) of the snailfish Careproctus colletti was collected by gill-net at Donghae-si, East Sea, Korea. This species is characterized by having the slender and stick-like teeth, lower end of gill opening not reaching to upper origin of pectoral fin, rays of lower part of pectoral fin long, reaching behind anus and margins of dorsal and anal fin dark. We described it as the first record to Korean fish fauna, and proposed the new Korean name "Meok-bun-hong-kkom-chi" for this species.

Feeding habits of juvenile Liparis tanakai collected from the eelgrass bed in Kwangyang Bay were studied. L. tanakai (2.0-6.0 cm SL) was a carnivore which consumed mainly amphipods (caprellids and gammarids) and caridean shrimps. Its diets also included a large amount of copepods, polychaetes and small fishes. Three distinct ontogenetic feeding groups were noted: (1) the individuals of 2.0-2.5 cm SL preyed heavily on copepods, (2) individuals of 2.5-4.0 cm SL fed mainly on amphipods. (3) individuals over 4.0 cm SL preyed mainly on caridean shrimps and small fishes. The dietary breadth of each size class showed relatively low value, and this means that juvenile L. tanakai depends on only few kinds of food organisms.

Snailfish usually lives at the bottom of the sea and showed typical retrogressive change with specialized tissue structures of skin and skeletons. In order to obtain the specific genes of snailfish, highly expressed in the body, we made subtracted cDNA library and analyzed 200 clones. Totally 200 clones were obtained and sequenced, and among them 62 clones were turned out to be homologous to the known gene, i.e., thioesterase (9), myosin (8), creatine kinase (7), skeletal alpha-actin (6), parvalbumin b (5), ribosomal protein (5), type I collagen (3), muscle troponin (3), dopamine receptor (2), histatin (2), and heat shock protein (2), cystatin (1), lectin (1), statherin (1), secretory carrier membrane protein (1), keratin type I (1), desmin (1), chloroplast (1), muscle tropomyosin (1), reticulum calcium ATPase (1), ribonucleoprotein (1). The remaining 138 clones were low homologous or non-redundant genes through Genbank search. Especially 5 clones were novel and specifically expressed in the body tissues of Snailfish by in situ hybridization. Therefore, we analysed these 5 clones to identify the C-terminal protein structures and motifs, and partly defined the roles of these proteins in comparison with the expression patterns by in situ hybridization. C9O-77, about 5000 bp, was supposed to be a matrix protein expressed strongly positive in epithelium, myxoid tissue, fibrous tissue and collagenous tissue. C9O-116, about 1500 bp, was supposed to be a transmembrane protein which was weakly expressed in the fibrous tissue, epithelium tissue, and myxoid tissue, but strong in muscle tissue. C9O-130, about 1200 bp, was supposed to be an intracytoplasmic molecule usually in the epithelial cells. C9O-161, about 2000 bp, was weakly expressed in epithelium, muscle tissue and myxoid tissue, but specially strong in epithelium. C9O-171, about 1000 bp, was supposed to be a transcription factor containing zinc finger like domain, which was intensely expressed in the epithelium, muscle tissue, fibrous tissue, and in collagenous tissue.

The diet composition of Tanaka's snailfish, Liparis tanakae were collected by bottom trawl net in the Yellow Sea of Korea during 2022 (April, August, October, and November). The size of the specimens ranged from 3.8 to 52.2 cm in total length. L. tanakae were primary consumed caridea shrimps (Crangon hakodatei, Eualus spathulirostris, etc.) and specialist feeder mainly consumed caridea shirmps (C. hakodatei). The L. tanakae's trophic level is 3.63. Caridea shrimps were the primary prey items for all size groups (<20 cm, 20~30 cm, 30~40 cm, ≥40 cm). The proportion of E. spathulirostris has increased as the body size of L. tanakae increased, whereas the proportion of C. hakodatei decreased gradually. As the body size of L. tanakae increased the mean weight of prey per stomach (mW/ST) tended to increase significantly (One-way ANOVA, P<0.05). The caridea shrimps were the primary prey items throught all seasons. In summer, the main prey items were the C. hakodatei, however, in autumn, the proportion of C. hakodatei decreased while the proportion of E. spathulirostris increased.
